What is being checked

info: WTMX - SKOKIE, IL
From the NRSC list: 101.90 MHz, PI code 8823, FCC facility 6377.
info: RadioDNS lookup name
10190.8823.8a0.fm.radiodns.org (frequency 101.90 MHz, PI 8823, country code 8a0)

1. RadioDNS registration

pass: Registered
10190.8823.8a0.fm.radiodns.org points to the station's authoritative domain: radiodns.hubbardradio.com

2. Service discovery (SRV records)

pass: _radiospi._tcp.radiodns.hubbardradio.com published
priority 10, weight 5, port 443 -> radiodns.hubbardradio.com [target is an alias of dcmqfs8ti5c7m.cloudfront.net]
warn: SRV target radiodns.hubbardradio.com is a CNAME alias
DNS rules (RFC 2782) say an SRV record should point at a name that has address records directly, not at an alias. Many resolvers cope, some do not.
What to do: Give radiodns.hubbardradio.com its own A/AAAA record (or point the SRV record at the real host name).
pass: _radioepg._tcp.radiodns.hubbardradio.com published
priority 10, weight 5, port 80 -> radiodns.hubbardradio.com [target is an alias of dcmqfs8ti5c7m.cloudfront.net]
warn: SRV target radiodns.hubbardradio.com is a CNAME alias
DNS rules (RFC 2782) say an SRV record should point at a name that has address records directly, not at an alias. Many resolvers cope, some do not.
What to do: Give radiodns.hubbardradio.com its own A/AAAA record (or point the SRV record at the real host name).
info: _radiovis._tcp: not published
Slideshow/visuals (STOMP) - optional, only needed for a live slideshow service.
info: _radiopush._tcp: not published
Slideshow/visuals (Server-Sent Events) - optional, only needed for a live slideshow service.
info: _radiovis-http._tcp: not published
Slideshow/visuals (HTTP) - optional, only needed for a live slideshow service.

3. Service Information file (SI.xml)

pass: HTTPS endpoint https://radiodns.hubbardradio.com/radiodns/spi/3.1/SI.xml answered
54 ms, 174,831 bytes
pass: The HTTPS certificate is valid
pass: Content type is application/xml
warn: SI file has no caching headers
What to do: Add Cache-Control: max-age (for example 86400 for 24 hours). Without it, receivers guess - and some ignore the content.
warn: The file does not strictly follow the official SI schema (3.1)

What to do: Many receivers are forgiving, but strict ones may ignore a file that does not match the schema. RadioDNS's SI tool (si.radiodns.org) can rebuild a correct file.
